By the way, in order to bring the self-propelled crusher into the work site where the work space is limited and to operate it without excess or deficiency, the machine body should be as compact as possible and the running performance should be stable. You are required to However, if the engine is placed behind the machine body as in the conventional example, the hopper, crusher, and engine are lined up in series to increase the length of the machine body in the front-rear direction, and the center of gravity is located behind the bogie to stabilize the machine. A slow movement is required to carry out the required running.

Moreover, if the engine is to be arranged behind the machine body, interference with the conveyor must be avoided, and as a result, the position of the center of gravity of the engine becomes high and stability is lost. Furthermore, in such a case, the rear surface of the crusher is closed by the engine, which makes maintenance of the crusher difficult.

Further, above the feeder between the hopper and the crusher, a foreign matter which is not desirable for the crusher, such as wood, papers, rebars and scraps, is manually removed before crushing to improve the crushing efficiency. It has become a space. However, regarding this work space,
As described above, a sufficient space cannot be secured because the size of the machine body in the front-rear direction cannot be increased. If a sufficient working space cannot be secured, not only the workability of removing foreign matter will deteriorate, but also there will be the problem that it will not be possible to secure a place where workers can safely wait when throwing construction waste into the hopper with a shovel. is there.

The present invention has been made in view of the above circumstances, and a first object thereof is to provide a compact self-propelled crusher capable of exhibiting stable running performance, and a second object thereof. The purpose is to provide a self-propelled crusher that can secure a sufficient working space and enhance the crushing efficiency, and the third purpose is to provide a self-propelled crusher that is excellent in assembly and maintenance. .

[0009]

A first aspect of a self-propelled crusher of the present invention is a crusher, a power source for driving the crusher, and a crushed object conveyed to the crusher. It comprises a feeder and a self-propelled carriage on which these are mounted, and the crushing device is arranged such that its center of gravity is located on one side with respect to the center of the self-propelled vehicle in the front-rear direction. The gist is that the self-propelled vehicle is arranged on the other side with respect to the center in the front-rear direction.

According to the first aspect, since the power source as a heavy load and the crushing device are arranged in front of and behind the self-propelled carriage, the weight balance of the machine body can be stabilized.
Further, since the crushing device is not connected to the power source, an open space is formed around the crushing device, which facilitates maintenance of the crushing device.

A second embodiment of the self-propelled crusher is equipped with a self-propelled crusher, a power source for driving the crusher, a feeder for conveying the crushed object toward the crusher, and these components are mounted. The gist is that the power source and the feeder are arranged side by side on the left and right.

According to the second aspect, since the power source and the feeder are arranged side by side on the left and right, the length of the traveling carriage in the front-rear direction can be shortened. This greatly improves the transportability and makes it easy to carry it to the site. Then, by allocating the space created by shortening the total length to the expansion of the work space, it becomes possible to reliably remove foreign matter that is not desirable for the crusher before crushing, eliminating clogging of foreign matter and improving crushing efficiency. You can

A third form of the self-propelled crushing machine is equipped with a crushing device, a power source for driving the crushing device, a feeder for conveying the crushed object toward the crushing device, and a feeder for carrying the same. It is provided with a self-propelled carriage, the power source and the feeder are arranged side by side on one side with respect to the longitudinal center of the self-propelled carriage, and the crushing device is arranged on the other side. .

According to the third aspect, since the power source and the feeder are arranged side by side on the opposite side of the heaviest crusher, the self-propelled crusher can be made compact and the weight balance can be stabilized. Can be achieved.

A fourth form of the self-propelled crusher is a crusher, a power source for driving the crusher, a hopper into which a material to be crushed by the crusher is charged.
The hopper is equipped with a feeder that conveys the object to be crushed into the hopper toward the crushing device, and a self-propelled carriage on which these are mounted.A power source and a hopper are provided on either side of the front and rear of the self-propelled carriage. The gist is that they are arranged side by side on the left and right, and the crushing device is arranged on the other side.

According to the fourth mode, since the power source and the hopper are arranged side by side on the opposite side of the crushing device having the largest weight, the compactness and the stabilization of the weight balance are achieved as in the third mode. Can be achieved.

A fifth embodiment of the self-propelled crusher is a crusher, a power source for driving the crusher, a hopper into which a material to be crushed by the crusher is put.
The hopper is equipped with a feeder that conveys the object to be crushed into the hopper toward the crushing device, and a self-propelled carriage on which these are mounted, and a hopper is provided near one of the front and rear ends of the self-propelled carriage. It is arranged that the crushing device is arranged on the other side.

According to the fifth aspect, since the distance between the hopper and the crushing device can be increased, the feeding path of the feeder can be lengthened. As a result, it is possible to reliably remove small-sized objects to be crushed that do not need to be put into the crushing device. Further, since the work space for removing foreign matter is expanded by expanding the feeder transport path, foreign matter can be reliably removed.

A sixth form of the self-propelled crusher is a crusher, a power source for driving the crusher, a hopper into which a material to be crushed by the crusher is put,
The hopper is equipped with a feeder that conveys the crushed material toward the crushing device, a discharge conveyor that discharges the crushed material crushed by the crushing device to the outside, and a self-propelled carriage on which these are mounted. The power source and the hopper are arranged side by side on one side of the center of the self-propelled vehicle in the front-rear direction, and the crushing device and the discharge conveyor are arranged on the other side.

According to the sixth aspect, the length of the discharge conveyor can be shortened because it is not necessary to extend the discharge conveyor through the power source as in the conventional case. As a result, the crusher can be made compact.

A seventh form of the self-propelled crusher is equipped with a crushing device, a power source for driving the crushing device, a feeder for conveying the crushed object toward the crushing device, and these components. The gist of the present invention is to provide a foreign matter selection device, which is equipped with a self-propelled carriage and which selects foreign matter contained in the crushed material conveyed by the feeder, above the feeder. The foreign matter sorting device can be configured by a so-called magnetic separator that attracts foreign matter contained in the crushed object by using magnetic force.

Conventionally, since the foreign matter sorting device is arranged on the downstream side of the crushing device and above the carry-out conveyor, the clogging of the crushing device due to, for example, a reinforcing bar cannot be eliminated. However, according to the seventh embodiment, the crushing device is Since the reinforcing bars can be removed on the upstream side, it is possible to avoid clogging of the crushing device and damage to the belt of the discharge conveyor.

In each of the above-mentioned forms, the feeder can be arranged offset to either the right or left side of the self-propelled carriage.

In each of the above-mentioned embodiments, a discharge conveyor for discharging the crushed material crushed by the crushing device to the outside can be provided, and this discharge conveyor can be arranged offset to either the right or left side of the self-propelled carriage.

In each of the above-mentioned embodiments, the feeder can be extended so that the conveyance route of the object to be conveyed by the feeder extends from the front side to the rear side of the center of the self-propelled vehicle in the front-rear direction.

In each of the above modes, the power source can be installed vertically along the front-rear direction of the self-propelled carriage.

Further, in the structure in which the traveling crawlers are provided on the left and right sides of the self-propelled carriage and the power source and the feeder are arranged side by side, the parts are attached to and detached from the power source located near the traveling crawler. The power source can be arranged so as to be displaced in the front-rear direction with respect to the traveling crawler so that a working space can be secured. As a result, since the traveling crawler does not exist below the power source, it is possible to work from below the power source when accessing the power source for maintenance or the like. It should be noted that shifting the position in the front-back direction means that the end portion of the traveling crawler and the power source are partially viewed from a plane as long as the traveling crawler does not hinder the work when accessed from below the power source. Overlapping arrangements are also included.

An engine is used as the power source,
In the case where the removable component has an oil outlet portion, if this oil outlet portion is arranged away from the end of the traveling crawler in the front-rear direction, for example, opening / closing operation of the drain cock of the engine oil pan, etc. You will be able to perform work that can only be accessed from the lower side of the engine. Therefore, in the oil change work that needs to be performed regularly,
It becomes possible to carry out the oil change work easily and safely directly from the ground without climbing on the ladder or the body. Further, even if the lower part of the engine such as the oil pan and its gasket is removed and replaced, the worker can enter below the power source and perform repair work from the ground without removing the engine from the self-propelled carriage. .

In addition, when a hydraulic pump is attached to the engine as the power source, if this hydraulic pump is arranged away from the end of the traveling crawler in the front-rear direction, when assembling the self-propelled crusher. In addition, it is possible to connect the hydraulic piping from the lower side of the hydraulic pump, which facilitates quick assembly work.
It can be done easily.

In each of the above-mentioned embodiments, the feeder includes a comb tooth-shaped portion having a through hole for dropping small pieces contained in the object to be crushed and not requiring crushing, and a plate portion having no through hole. And the plate portion can be arranged near the charging port of the crushing device.

In each of the above modes, a fence can be installed near the hopper and the input port of the crushing device. According to this configuration, the distance between the hopper and the crushing device can be made larger than in the past, so when doing work in high places at this part, a place to leave the body can be obtained, and the safety of the worker must be secured. Further, since the work can be performed with peace of mind, the efficiency of the foreign matter removing work can be improved.

1 is a plan view of a first self-propelled crusher according to the present invention, FIG. 2 is a side view of the self-propelled crusher as seen from the left side in the traveling direction, and FIG. Similarly, it is a side view seen from the right side, FIG. 4 is a front view of the self-propelled crusher, and FIG. 5 is a rear view thereof (however, the rising portions of the crusher and the conveyor are omitted).

In each figure, the traveling direction of the self-propelled crusher is forward (F), the direction opposite to the traveling direction is rear (A), the left side toward the traveling direction is left (L), and the traveling direction is toward the traveling direction. The right side is right (R) and the upper side is up (U).

1 and 2, the self-propelled crusher is
It is a kind of recycling machine for crushing and reusing construction waste materials (crushed materials) such as concrete debris and rocks generated when dismantling buildings and bridges. Self-propelled carriage 1 and this self-propelled carriage 1 and a machine body 2 mounted on the machine 1.

The self-propelled carriage 1 comprises a frame 3, left and right crawler frames 4 and crawlers 5, and the both side crawlers 5 are individually driven to rotate by the left and right traveling hydraulic motors 6 for traveling.

The machine body 2 is provided with a hopper 7 at the front end of the self-propelled carriage 1, and the construction waste material put into the hopper 7 is conveyed to the rear side of the main body by a feeder 8 so that the self-propelled carriage 1 can be driven. It is adapted to be put into the crusher 10 arranged at the rear end portion.

The crushed material crushed by the crusher 10 is
It is discharged from the lower part of the crusher 10 by the discharge conveyor 11 which is arranged in a slanting manner (see FIG. 2).

In this construction, the center of gravity of the crusher 10 which is the heaviest item is arranged rearward of the center position of the self-propelled carriage 1 in the front-rear direction, and the engine 9 which is another heavy item.
Means that its center of gravity is arranged on the front side with respect to the center position of the self-propelled carriage 1 in the front-rear direction. Further, the hopper 7 and the engine 9 are arranged side by side on the front side.

The center of gravity G of the machine body 2 is the center position of the self-propelled carriage 1 (the intersection of the center line C1 in the left-right direction of the self-propelled carriage 1 and the center line C2 in the front-rear direction thereof in FIG. 1). .) Does not necessarily match, but it is preferable to substantially match the two in order to secure the traveling stability of the self-propelled carriage 1 on which the machine body 2 is mounted. FIG. 1 shows a case where the two are matched.

Specifically, as shown in FIG. 1, the crusher 10, the feeder 8 and the hopper 7 are aligned with their center lines C3 in the left-right direction, and the center line C3 is set in the left-right direction of the self-propelled carriage 1. It is slightly eccentric to the left with respect to the center line C1. On the other hand, the engine 9 is placed vertically along the front-rear direction, and is arranged close to the right end in the left-right direction so that it can be arranged on the right side of the hopper 7 within the width of the self-propelled carriage 1.

With this configuration, the length of the machine body 2 in the front-rear direction can be shortened by the width of the engine 9 at the maximum, as compared with the case where the engine 9 is arranged behind the machine body 2 as in the conventional case. it can.

On the other hand, there is a vacant space above each crawler 5 on both the left and right sides of the hopper 7, and even if the engine 9 is arranged in this vacant space, the width of the machine body 2 in the lateral direction increases. There is no. Therefore, since the machine body 2 can be made compact by such an arrangement, even if there are restrictions on the vehicle width and the vehicle length when the self-propelled crusher is carried into the site, it can be cleared. It is possible to fully demonstrate the self-propelled ability in a narrow field.

With this arrangement, the machine body 2
The front, back, left, and right balance is maintained. That is, in the self-propelled crusher, since the weight of the machine body 2 equipped with the crusher 10 is large, if the front, rear, left and right of the machine body 2 are not well balanced, the load applied to the both-side crawlers 5 of the self-propelled carriage 1 equipped with the machine body 2 will be reduced. It becomes uneven. When the load of the traveling hydraulic motor 6 is different between the left and right, the straight traveling performance is deteriorated and the work on the slope becomes unstable.

However, in this embodiment, since the front-rear and left-right balance of the machine body 2 is maintained as described above, such a problem does not occur, and the stable traveling performance of the self-propelled carriage 1 equipped with the machine body 2 is eliminated. Is always secured. In addition, the load is less likely to collapse even during high-speed transportation by the trailer, and safety can be improved.

An arrangement opposite to the above, for example, the crusher 10 is arranged in the front and the hopper 7 and the engine 9 are arranged in the rear, or the direction in which the crusher 10 is eccentric and the direction in which the engine 9 is offset are set. It goes without saying that the above may be reversed to the above.

Hereinafter, each component will be described in more detail.

In FIG. 4, the hopper 7 has a large rectangular opening on the upper side, and the opening area is narrowed downward. From the opening, construction waste carried by a hydraulic excavator or the like is thrown in. ing.

Corresponding to the above-described relationship between the center lines C1 and C3, the center line C3 'of the support frame (not shown) of the hopper 7 in the left-right direction is the center line C1' of the self-propelled carriage 1 in the left-right direction. Since it is slightly eccentric to the left, the machine body 2
There is a large free space on the right side of. Therefore, even if the engine 9 is placed vertically on the right side of the hopper 7, there is no risk of the hopper 7 interfering with the engine 9, and even if the engine 9 is placed, the hopper 7 that is the maximum height of the machine body 2 is raised. You don't even have to.

Returning to FIG. 1, description will be made.

The feeder 8 is a grizzly feeder provided with four stages of grizzly 81 having comb-like parts arranged below the hopper 7, and the feeder 8 is vibrated by a feeder hydraulic motor (not shown). Thus, the construction waste materials falling from the hopper 7 are sequentially conveyed to the crusher 10, and the fine earth and sand adhering to the construction waste materials and the small pieces that do not need to be crushed during the conveyance are gravity-dropped from the interstices of the comb-teeth portion, Construction waste materials with a size larger than this gap are selected.

In the present embodiment, the machine body 2 is made compact by placing the engine 9 vertically and arranging it on the side of the hopper 7 as described above, so that the space between the crusher 10 and the hopper 7 is reduced. It is possible to take a larger space than before. Then, due to the expansion of the space, the grizzly 81 is extended from the front side to the rear side of the center C2 (see FIG. 1) in the front-rear direction of the self-propelled carriage 1, and the grizzly 81 is moved in the front-rear direction. Four
It is possible to provide steps (81a to 81d).

FIG. 6 shows the feeder 8 and the crusher 1.
It is the figure which showed the contact part with 0 typically, (a) is a side view, (b) is a top view.

Each of the grizzlies 81a to 81d has a comb-teeth shape extending forward and backward by a predetermined length, and is arranged in a descending step shape from front to back. With this configuration, the feeder 8
Is vibrated, the construction waste material is sequentially conveyed from the grizzly 81a on the most upstream side to the grizzly 81d on the most downstream side by the vibration, and during this time, it is necessary to crush from the gaps of each grizzly 81. Since the small pieces which are not present are removed by gravity fall, sufficient sorting ability can be secured, and as a result, the load on the crusher 10 is reduced.

Further, the feeder 8 is provided with a plate portion 81e further downstream of the most downstream grizzly 81d. Since the plate portion 81e is not formed with a through hole through which a small piece that does not need to be crushed is dropped, foreign matter can be removed without being obstructed by the gap of the comb tooth-shaped portion of the grizzly.

When the distance between the crusher 10 and the hopper 7 is the same as the conventional one, and the grizzly 81 is constituted by two stages of the conventional constitution, the conventional engine arrangement space can be omitted, so that the engine can be omitted. It is possible to shorten the discharge conveyor 11 that has been extended by passing below 9. Thereby, the machine body 2 can be made compact.

In FIG. 5, on the left side of the feeder 8 (on the side opposite to the engine 9), there is provided a working deck 82 provided with a handrail as a fence and a ladder 83 for going up and down with respect to the working deck 82. ing. The worker is this ladder 83
It is possible to remove foreign substances such as reinforcing bars, iron scraps, wood, papers, etc. from the construction waste materials being conveyed on the grizzly 81 from above to the work deck 82.

It is preferable to secure a wide space for the work deck 82 in order to ensure the workability and safety of the worker. Therefore, as described above, if the space between the crusher 10 and the hopper 7 can be made larger than in the conventional case, the length of the working deck 82 in the front-rear direction can be expanded accordingly. As a result, as shown in FIG. 2, when the construction waste is put into the hopper 7 by the shovel, the worker can move away from the work range of the bucket B and evacuate backward.

In FIG. 3, the crusher 10 is constituted by a so-called jaw crusher which swings the moving teeth (swing jaws) 101 with respect to the fixed teeth 102 to crush the teeth between both teeth. The upper ends of the moving teeth 101 are eccentrically attached to a rotating shaft (eccentric shaft) 103, and the lower ends of the moving teeth 101 are supported by a toggle block 101a fixed to a frame via a toggle plate (not shown). Has been done. By adjusting the fixed position of the toggle block 101a with respect to the frame in the front-back direction, it is possible to set the minimum gap between the moving teeth 101 and the fixed teeth 102, thereby adjusting the particle size of the crushed pieces. It has become. A tension spring 101b is provided between the back surface of the moving tooth 101 and the frame.

The rotary shaft 103 is rotated by a crusher hydraulic motor 104. Then, the crusher hydraulic motor 104 is driven to rotate the rotary shaft 103 to eccentrically rotate the upper end portion of the moving tooth 101 and move the lower end portion of the moving tooth 101 so as to draw a predetermined locus. The moving tooth 101 is caused to swing with respect to the fixed tooth 102.

The discharge conveyor 11 has a horizontal conveying portion arranged below the crusher 10 and an inclined conveying portion inclined upward from the horizontal conveying portion. The inclined conveying portion is directed toward the upper rear part of the machine body. It has been extended. Then, the crushed material crushed to a predetermined size by the crusher 10 is placed on the endless belt 111 which is circulated and driven by the driving force of the conveyor hydraulic motor 112, and is conveyed on the belt 111 conveyance path. The magnetic separator 12 provided in the above magnetically attracts and removes the reinforcing bars, iron scraps and the like contained in the crushed material being conveyed.

In this embodiment, the discharge conveyor 11 is arranged substantially at the center of the machine body in the left-right direction.
In order to easily perform the maintenance of No. 1, it may be eccentrically arranged on one of the left and right sides.

As shown in FIG. 1, the magnetic separator 12 is equipped with a permanent magnet 123 inside the endless belt 122 driven by the magnetic motor 121 for magnetic separator, and is substantially orthogonal to the belt running direction of the discharge conveyor 11. The endless belt 122 is arranged in the direction. Then, the magnetic force of the permanent magnet 123 is made to act on the discharge conveyor 11 via the endless belt 122, and the rebar and iron scraps of the crushed material moving on the discharge conveyor 11 are adsorbed to the endless belt 122.

FIG. 7 schematically shows the foreign matter removing operation by the magnetic separator 12.

First, in FIG. 10A, the permanent magnet 123 is
By the magnetic force of, the rebar S, iron scraps, and the like on the discharge conveyor 11 are adsorbed. Next, when the rebar S is adsorbed by the traveling of the endless belt 122 as shown in FIG. 2B, the rebar S is taken out from the transport path of the discharge conveyor 11. Next, as shown in FIG. 7C, when the reinforcing bar S is conveyed to a place where the magnetic force is weak, the reinforcing bar S naturally comes off the endless belt 122 and is discharged to the chute 124.

In the above embodiment, the magnetic separator 12 having the above structure is arranged on the conveying path of the discharge conveyor 11, but
Instead of this or in addition to this, it may be arranged above the feeder 8. When the magnetic separator 12 is arranged above the feeder 8, the reinforcing bars S and iron scraps can be removed before the material to be crushed is put into the crusher 10.

Since the crusher 10 is arranged at the rearmost portion in the arrangement of this embodiment, the discharge conveyor 11 is different from the conventional structure in which the crusher is arranged at the center of the machine body.
It is possible to shorten the length of the horizontal portion at. As a result, the processed crushed material can be conveyed by the conveyor having a smaller conveying capacity than the conventional one.

Further, the engine 9 drives a hydraulic pump (not shown), and by supplying pressure oil from the hydraulic pump to the hydraulic motors via a control valve (not shown), the hydraulic motors are driven. The engine 9 and hydraulic equipment such as a hydraulic pump and a control valve may be centrally arranged as an integrated power unit.

In the above-mentioned arrangement, unlike the case where the engine is arranged rearward as in the conventional example, it is not necessary to arrange the engine upward in order to avoid interference with the discharge conveyor 11, and the engine 9 runs. It can be installed at the lowest possible position on the work crawler 5, further improving the stability and maintainability of the machine body 2.

The operation of this self-propelled crusher will be described below.

In FIG. 1, when the construction waste material carried by a hydraulic excavator or the like is put into the hopper 7 arranged on the front side of the machine body, the construction waste material put in is guided to the inner wall inclined surface of the hopper 7 and fed to the feeder 8. Fall on the grizzly 81. When the grizzly 81 of each stage is vibrated by the feeder hydraulic motor, the construction waste material is sequentially moved toward the crusher 10 by the feeder. During the transportation, small pieces contained in the construction waste material fall from the lattice gaps of the grizzly 81 at each stage and are received on the belt 111 of the discharge conveyor 11.

Further, when the construction waste material is conveyed by the feeder 8, the worker is raised to the work deck 82, and foreign matters such as reinforcing bars, iron scraps, wood, and paper mixed in the construction waste material are manually operated. To be removed.

Next, the crushed material is the crusher 1 in operation.
It is thrown in 0.

The construction waste material from which foreign matter has been removed beforehand is crushed by the crusher 10 so that the moving teeth 101 and the fixed teeth 102 can be removed.
By being crushed to a predetermined size between and, the particles are aligned to a predetermined size and fall on the belt 111 of the discharge conveyor 11 located below the crusher 10.

Next, the crushed material is conveyed to the rear of the machine body together with the small pieces by the discharge conveyor 11. At this time, the magnetic separator 12 removes the reinforcing bars, iron scraps, and the like contained in the crushed material and the small pieces. Next, the treated crushed material P from which the metals have been removed is discharged from the rear end of the discharge conveyor 11 to the outside of the machine body (see FIG. 2).

In the above embodiment, a so-called grizzly feeder is used, but the present invention is not limited to this, and a so-called plate feeder or the like that drives a bottom plate by a hydraulic motor to sequentially convey construction waste materials may be used. You can also

Further, although the magnetic separator 12 is provided in order to remove the metal as the foreign matter in the above-mentioned embodiment, the magnetic separator 12 may be used in place of the magnetic separator 12 or at the work site where a large amount of foreign matter having a small specific gravity is generated. In addition to 12, it is also possible to provide a wind power sorter that blows away foreign matter by wind pressure.

Further, in the above embodiment, the machine body 2 is mounted on the crawler type self-propelled carriage 1, but the invention is not limited to this, and the machine body can be mounted on the wheel type self-propelled carriage.

It is eccentric. On the other hand, the engine 211 is placed vertically along the front-rear direction and arranged side by side on the right side of the hopper 207 within the width of the self-propelled carriage 201. In the figure, 212 is a magnetic separator,
O is a worker.

Next, the arrangement of the engine 211 and the hydraulic pump 213 will be described in detail.

The engine 211 of the second self-propelled crusher 200 is
As shown in the front view of FIG. 10, it is arranged above the traveling crawler 205, but as shown in FIG. 8, the rear end portion 205a of the traveling crawler 205 is arranged as a starting end in a column above and behind the traveling crawler 205. Has been done.

In the layout in which the engine 211 is mounted on the side of the feeder 208, the vehicle width cannot be expanded unnecessarily, so the engine 211 must be placed on the traveling crawler 205. At this time, if the vehicle height is lowered with the configuration in which the engine 9 is arranged on the traveling crawler 5 as in the configuration shown in FIG. 3, the oil pan 9a and the traveling crawler 5 are separated from each other when oil is changed, for example. The oil receiving container cannot be inserted to the lower side of the oil pan 9a due to the narrow interval between the oil pan 9a, and the oil is discharged from the oil discharge port (drain cock or drain plug as a component that is detachable from the power source). You will not be able to receive the oil.

Therefore, it is necessary to connect a separately prepared hose to the drain cock and suck the oil to discharge the oil, which complicates the work.

If a space below the engine 211 for a worker is not secured, a gap S on the traveling crawler 205 is usually used to open and close the drain cock 211a provided below the engine 211. (See 4)), and it is difficult to see the drain cock 211a, and the operator is burdened.

Further, not only oil replacement but also other engine maintenance work cannot be performed directly from below the engine. Specifically, in FIG. 8, when oil leaks from the seal surface of the oil pan 211b mounting portion, the oil pan mounting bolt is removed to remove the oil pan 21b.
Although 1b will be removed and the gasket will be replaced, if the traveling crawler 5 is located below the engine 211 as in the conventional case, the oil pan 211b cannot be removed either. In this case, the engine 211 is temporarily lowered from the machine main body 202 to work. Therefore, maintenance workability becomes extremely poor. The oil pan 211b is also regarded as a component that is attached to and detached from the power source.

On the other hand, in this embodiment, the oil pan
Since the traveling crawler 205 does not exist below 211b, the worker O can enter below the oil pan 211b, and the oil pan 211b can be removed downward. In the figure, a shaded portion 211b 'indicates a state in which the oil pan is removed from the engine 211.
There is sufficient working space below 1. More specifically, a work space for attaching and detaching a component that can be detached only to the lower side or the diagonally lower side of the power source is secured.

If the oil pan 211b can be removed downward, the oil pan 211b does not necessarily have to be in the vertical direction, and may be moved obliquely forward or backward or sideways to be removed. That is, as shown in FIG. 8, a part of the engine 211 may be arranged above the rear end portion 205a of the traveling crawler 205. By doing so, the total length of the self-propelled crusher 200 can be shortened.

A hydraulic pump 2 is attached to the output shaft of the engine 211.
13 is connected, and this hydraulic pump 213 is connected to the engine 211.
Is used as a drive source to supply pressure oil to the hydraulic circuit.

The arrangement of the hydraulic pump 213 and the traveling crawler 205 will be described below.

When the engine 211 is arranged in front of the rear end portion 205a of the traveling crawler 205 as the start end, when the engine 211 is arranged with the cooling fan 211c behind, the hydraulic pressure provided on the opposite side of the cooling fan 211c. Pump 213
The traveling crawler 205 can be arranged so as not to overlap in the vertical direction.

If the traveling crawler 205 is disposed below the hydraulic pump 213, the hydraulic pump 213 cannot be accessed from the lower side during assembly work or maintenance, resulting in poor workability. Specifically, hydraulic pump
It is necessary to connect a lot of piping and wiring to 213,
Tightening work is required for each pipe. In this case, the hydraulic pump 213
If the tightening work cannot be performed from below, there will be a tightening part where the spanner cannot be turned.

Therefore, as shown in FIG.
If 213 is placed at a position where it does not interfere with the traveling crawler 205,
Piping and wiring can be easily installed, and workability is greatly improved. Further, since the worker can perform the above-mentioned maintenance work such as attaching and detaching the parts downward while standing on the ground without climbing on the ladder or the machine body, the safety of the work can be improved.

In the above-described embodiment, the radiator side, which is the cooler of the engine, is arranged rearward, and the hydraulic pump is arranged on the front side thereof, that is, on the front end side of the machine body. However, the structure is not limited to this, and the engine may be arranged in the opposite direction, and the radiator may be arranged on the front end side of the machine body and the hydraulic pump may be arranged on the rear side of the engine. With this reverse orientation, the cooling efficiency of the engine can be increased, and the pipes that connect the hydraulic pump and the actuators such as the crusher motor and the conveyor motor can be shortened. The cost can be reduced as well.
